which side is bank 1
I am getting bad coil reading from the downstream bank 1.
I'm getting code P 0420. Looking at the O 2 sensor I'm getting high readings.
Going to replace with a denso.

I replaced the O2 sensor, quick easy job. but then the front one started giving weird signals. I have ordered bank one upstream front left O2 sensor.
